Congratulation .

You meant capacity or voltage? Because we are able to charge 12V battery with 3V source with radiant method.

I have two way to charge a battery

- the top is for conditioning (almost never do that because the bottom one also do it)
- the bottom for everyday charging

That is weird, what is the current consumption?

Yes, that is the way to save transistor. But I don't think we need that. Putting a diode like that kill the radiant and waste them.

More importantly, it force the coil to draw more power. Notice that the coil consumption will at least double if you do that. Current consumption on a radiant circuit will usually increase if you utilize or diode short the radiant part. My stingo do not but self oscillation terminate instead.

still learning at that time, still wondering now, but I believe that is the flow.
